Figure 1 is a view of our improved tip-cart ready for loading. Figure 2 is a view of same after-discharging a load, showing our improvement.

We construct, of wood or metal, a framework, composed of the stringers A and A, the cross-pieces b, b,

and b, the uprights c and cjancl the cross-head piece 12.

Thecross-pieces b, b, and b" are secured to the stringers A and A by raves and bolts, andthe uprights c and c and cross-head piece at are'mortised together, and into the stringers A and Al, all as shown inthe ace bm panying drawings. V l v i We then construct, of weed or metal, the spindle-headed post E, which is secured and hraced by the crosspieces 6, b, and b,-, and the plate or circle F, which is supported by and secured to the braces g, g, g", and 9', all as shown in the accompanying drawings. I L I We then construct, of wood or metal, the rocker 1i, and the trundles I, and I, and I. I The rocker H is secured to the spindle-bolt, in the head of the'post E, so as to turn readily upon the same,

v When the load is to be discharged, the tail-board M is removed, and the fastenings land Z aredisconnected. The cart-body K is thentipped into the position shown in fig. 2, and the load is discharged.

When the load is to be discharged to either'side, the fastenings and Z- are disconnected, and the cart-body, with thoroeker H, is revolved upon the spindle-headed post E, until in the desired position, the trundles I, I, and I travelling upon the plate or circle F, serving to steady and support the load while turning. The tail- Until the tail-board is removed, the cart-body K may be kept from tipping by passing the hooked end of the rod n (or,n, as the case may he,) through the eye-bolt 0, or by some similar contrivancc.

This, mitten-r1 cart-body may be permanently mounted upon wheels or runners, as .may be desired, or placed upon any ordinary platform railroad-car, platform, cart, or truck for'teniporary use.
